Specication of Letters Patent.

"Application led October 11. 1910, Serial No. 586,584.v Renewed ctober'11,'1911. Serial 1105654251.

Beit known that I, CHARLES a citizen of the United States, and resident of New York city, in the county of New York and State of NewYork, have invented certain new anduseful Improvements in Dam Construction,of which the `following is a specification.

` My invention relates tov dam constructions, and' the object of my invention is to provide a hollow gravity dam of concrete or other suitable material which can be molded 'by pouring the material in false work.

tresses.` Fig. 3. is a view Anfurther object is to provide a construction in which the-walls or buttresses are arranged at an angle to the flow 'of the stream and are joined together, and also arranged so that the walls will be separated an equal distance from each other at most all points so that the deck willexpand and contract evenly and the weight of'the water willbe about evenly 'disposed between the -butf tresses.

A further objectis to provide a deck for the dam reinforced by metal or other suit; able rods which are embedded inthe deck and which extend across the buttlresses. y

Referring to the drawings which form a part of this specification, Figure 1. -is a cross sectional view of a dam embodying my construction and disclosing the rods in ot the dam to the top as shown, and are dicate a series of rods which run longitud# nally of the deck and are located below saidspaced evenly apart from each other apredetermined distance, and A2- 2,' etc., 1n-

Iirst rods. The deck is formed integral with 'and supported by the buttresses which'appear in plan to be arranged ina series of V shaped portions, one series havin the apex of the V- reversed in position re ative to the other-series adjacent thereto so that F. DOEBLER,

*the distance between the walls will be equal and thereforeA the spaces spanned by the Patented Dee. 5, 1911'.

deck will be ofequal width and the load of water will be more evenly,distributed be'- ltween the buttresses, and by-reason of the angular arrangement of the buttresses and the interlocking of same in pairs, a very, stable structure can be provided.

Thebuttresses are shown clearly iniFig. 2.v

and one seriesisindicated'by B-B--B, etc., 'shown in -section and dotted lines, and the adjacent -series is indicated by' O O-Q etc., the spaces being indicated by D-D- D-, etc. Where the bilttresses join each other they are preferablyextend- 'ed in a single short' wall'or buttressI indicated by E-E--E the purpose being to prevent too large an area'of thedeck to remain unsupported by a but-trees at the' points where these 'walls E are placed, as will be readily understood. By this arrangement of buttresses and'supporting rods, the rodsall cross the buttresses at frequent distances apart and thereby the entire deck lis most .perfectly adapted to carry the load of Water safely, and comparatively smaller rods may be used than in cases Where ,the rodsdo not so frequentlycross the buttresses.

Having thus described my invention I claim as new 1. A hollow gravity dam embodying aseries of separated independent V shaped buttresses arranged at an angle to each other and to the `fiow of the stream `and having a deck formed integral therewith and embodymg a series of rods embedded therein and extending across sald buttresses and a series of rods extending across saidbuttressesand.

said iirst rods.

2. A hollow gravity dam embodying a plurality of independent series of V shaped buttresses, oneseries being locatedin reverse position relative to theadjacent series. 3. A hollow'gravity dam .embodying a plurality of independent series of V shaped butt-resses, one series being arranged iure-. verse position relative to the ad]acentser1es; .and having a deck provided with reinforcing rods -embedded `therein and extending .across said buttresses.

4. A hollow gravity dam embodying a plurality of V shaped `buttresses' having walls arranged at an angle to the flow :of the v Q notarse stream and arran ed one behind the other in series, one series eing arranged in reverse position relative to the adjacent series, and having a deck provided with reinforcing rcdswhich extend across said buttresses.

5; A hollow gravity dam embodying a plurality of V shaped buttresses arranged at an angle to the flow of the stream and arranged one behind the other forming a se ries, and. a second series of like :form located adjacent to said rst series and arranged in reverse position, and a deck provided with reinforcing rods extending across said buttresses and having a second series of rods extending across said first rods.

6. A hollow gravity dani embodying a plurality of V shaped buttrcsses arranged at an angle to the flow of the stream and arranged'one behind the other forming a series, and a second series of like form located adjacent to said first series and arranged in reverse position, and a deck provided with reinforcing rods extendlng across said buttresses and longitudinally of the deck and having a second series ot' rods extending across said first rods and located above same.

7. A hollow7 gravity dam embodying buttresses arranged in series, each of which is V shape in form and having their Walls parallel to each other, each alternate series of buttresses having their ends reversed relative to the adjacent series.

8. A hollow gravity dam embodying buttresses arranged in series, each of which is i V shape in term and having their walls parallel to each other, each alternate series having their ends reversed relative to the adj acent series, andia short wall extending from the point where the buttresses join each other toward the junction of the adjacent buttress substantially as shown.

9. A hollow gravity dani embodying buttresses V shape in form and arranged one behind the other and spaced apart from each other at equal distances.

10. A hollow gravity dam embodying a plurality of series of V shaped buttresses placed one behind the other in each series, one series having the ends of the buttresses located on the down stream side of the darn and the adjacent'series having the ends of the buttresses located on the upstream side thereof, and a deck formed integral with said buttresses.

1l. A hollow gravity dam embodying a se-i ries of separated independent V shaped buttresses arranged at an angle to each other and to the flow of the stream and having a deck supported by said buttresses and embodying a series of rods embedded therein and extending across said buttresses and said first rods.

12. A hollow gravity. dam embodying a plurality of series of V shaped buttresses placed one behind the other in each series, one series having the ends of thebuttresses located on the down stream side of the dam and the adjacent series having the ends lof the buttresses located on the upstream side thereof, and a deck supported oy said buttresses. p
